Hi All,
I'm trying to use the Gem5 full system.
but It doesn't work.
These are my configurations
-kernel = vmlinux-4.19.83 (5.4.49 / 4.14.134)
-Ubuntu = ubuntu-18.04.6-live-server-amd64 (tried 16.04)
-gem5 = 21.1.0.2
-X86 architecture
-I will use an O3CPU and DRAMsim3.
I made an image by using qemu and I completed the booting system.
To make the image, I use this command "qemu-system -hda <ubuntu.img> -cdrom
<ubuntu.iso> -m 8G -enable-kvm"
The image size for ubuntu18.04.6 is 8.6GB.
All files are in ~/gem5/fs
and I changed "M5_PATH" to "/home/user/gem5/fs" in Syspath.py line 34.
As far as I know, These are all configurations to use the gem5 full system.
So I ran gem5. but it does not work.
I attached all command and error messages below.
How can I run the gem5 full system?
Please let me know.
Thanks in advance.
